BNC can upload clock and orbit corrections to Broadcast Ephemeris (Broadcast Corrections) in RTCM Version 3 SSR format. You may have a situation where clocks and orbits come from an external Real-time Network Engine (1) or a situation where clock and orbit corrections are combined within BNC (2).

(1) BNC identifies a stream as coming from a Real-time Network Engine if its format is specified as 'RTNET' and hence its decoder string in the 'Streams' canvas is 'RTNET'. It encodes and uploads that stream to the specified Ntrip Broadcaster Host and Port

(2) BNC understands that it is expected to encode and upload combined Broadcast Ephemeris Corrections if you specify correction streams in the 'Combine Corrections' table.

To fill the 'Upload Corrections' table, hit the 'Add Row' button, double click on the 'Host' field to enter the IP or URL of an Ntrip Broadcaster and hit Enter. Then double click on the 'Port', 'Mount' and 'Password' fields to enter the Ntrip Broadcaster IP port (default is 80), the mountpoint and the stream upload password. An empty 'Host' option field means that you don't want to upload corrections.

Specify a path for saving generated Broadcast Corrections plus Broadcast Ephemeris as SP3 orbit files. If the specified directory does not exist, BNC will not create such files. The following is a path example for a Linux system: /home/user/BNC${GPSWD}.sp3Note that '${GPSWD}' produces the GPS Week and Day number in the filename.

Specify a path for saving generated Broadcast Correction clocks plus Broadcast Ephemeris clocks as Clock RINEX files. If the specified directory does not exist, BNC will not create Clock RINEX files. The following is a path example for a Linux system: /home/user/BNC${GPSWD}.clkNote that '${GPSWD}' produces the GPS Week and Day number in the filename.

In case the 'Combine Corrections' table contains only one Broadcast Correction stream, BNC will add that stream content to the Broadcast Ephemeris to save results in files specified via SP3 and/or Clock RINEX file path. You should then define only the SP3 and Clock RINEX file path and no further option in the 'Upload Corrections' table.
